Dal-Rin was a male Voss Mystic living on Voss long before the Galactic War. After his death, he became the keeper of the dream-rock located in the Dark Heart of the Nightmare Lands and used in the Forbidden Ritual. In 3641 BBY Sith Lord Kallig and a Gormak named Hadrik used the dream-rock and performed the ritual, allowing Kallig to silence the Force ghosts inside their mind.
